Even for medium-sized projects, it doesn't.  For example, Linux kernel
development is quite difficult because no developer can build the
kernel in more than a few configurations, but there are more then
2**50 possible configurations.  As a result, it happens all the time
that one change breaks some special configurations, and there's really
no way to test automatically for such problems.
